GUI Licencing issues

Hi there,



I'm doing a survey of Linux embedded GUI Systems for a customer.



Looks like there are (at least) 4 GUI Options:


  • Fully fledged X-Window System (possibly using tiny-X)
  • Microwindows/Nano-X System probably using FLTK
  • Qtopia/QPE
  • MiniGUI

My question is about royalties now.



Microwindows/Nano-X is MPL, X-Window System is BSD-like, MiniGUI is GPL and Qtopia/QPE has a commercial Licence.



The customer should be able to generate proprietary GUI Interfaces without Licence violations.



So which Royalty-free Options does this give?



Sven

To clarify 2 things in your post:

1) Qtopia/QPE is dual-licensed from Trolltech. A GPL version (which requires you GPL your code written against it, but no royalties) and the commercial/closed-source version.

2) Last time I checked, the commercial version of QPE is available as a one-time fee with no per-unit royalties. However, I believe it is rather pricey.

FWIW,
